多功能LED设计，拥有自动和手动两种模式
1）自动模式，可以通过人体红外传感器检测是否有人，采用光敏电阻构成的电路检测环境光的强度，从而自动实现灯的开启和关闭，也可以根据环境亮度调节灯的亮度；
2）手动模式，可以使用WIFI连接手机，通过手机APP手动控制不同灯的开启和关闭，并可控制LED灯的亮度
单片机选用stm32f103c8t6；APP使用Android stutio环境编写；OLED为7脚，SPI
下面OLED显示图片手动模式对应上面手动模式介绍的功能，WIFI模式对应的手动模式介绍的功能
手机APP程序文件较大，压缩后仍大于20M，下面是网盘链接（第一次使用Android stutio写APP，可能还存在问题，欢迎大家指正）
